It seems as though the bosses at Twitter have splashed out lots of cash to pick up the TweetDeck platform. No official word has been released yet but the industry buzz has it that it cost a cool $40 million to snap up.

In fact some estimates go up to $50 million and state a mixture of cash and shares as being used. It seems as though the papers were signed on Monday, so if the stories are true it is all done and dusted already.

The TweetDeck deal was previously under threat as UberMedia was involved in a bidding war with Twitter to get hold of it. It now seems as though Twitter has won by gazumping their rival’s biggest bid of $30 million.

The only statement from Twitter sources was a rather inscrutable “we continue to not comment on rumours”.

If the rumours which they won’t comment on turn out to be true then the guys at Twitter can add TweetDeck to Tweetie and TwitPic in their growing stock pile of applications they have purchased.

TweetDeck works by letting users organize their tweets in an easy to manage dashboard which is a lot easier than using just Twitter. It is an Adobe Air application and is currently in public beta. The people behind it are UK based. It will be interesting to see what the future holds for this popular application once it joins the Twitter family.

Do you use TweetDeck? If so, what would you like to happen with the service?
